The bubble on my Theater Edition Luke in Jedi Knight is starting to come off. Just on the left side, but pretty much all the way down the left side of the bubble. See the pic if you want a look:

I know this is a very common issue due to the glue used on these, but what do you guys suggest I should do to this thing now? I know they're not worth much anymore, and I'm not too shook up anyway because the card was already in real rough shape.Any tips would be appreciated - thank you
